Japan's rapid urbanization has caused many of its indigenous spirits and ghosts to lose their homes. As a result, there has been an increase in homeless spirits, leading to the creation of a new profession called Ghost Sweeper (GS). These private exorcists are hired by those who can afford them and operate in a highly competitive corporate environment. The Mikami GS Company, led by Reiko Mikami and her two assistants, Tadao Yokoshima and Okinu, is considered to be the best among these Ghost Sweeper companies.
